Pluggable connector with differential pairs

Abstract

A pluggable connector that includes a housing having an inner surface that defines a housing cavity. The housing cavity extends along a central axis to an opening of the housing cavity. The opening is sized and shaped to mate with a mating connector moving along the central axis. The connector also includes a plug insert that is positioned within the housing cavity. The plug insert extends along the central axis and forms contact cavities therein that extend parallel to the central axis. The plug insert has an outer surface that is separated from the inner surface of the housing by a spacing. The connector also includes differential pairs. Each differential pair has two mating contacts that extend parallel to each other along a contact plane of the differential pair and within corresponding contact cavities. The contact planes of at least two adjacent differential pairs are perpendicular to one another.

Description

BACKGROUND OF THE INVENTION[0001]The invention relates generally to connectors, and more particularly to pluggable connectors for high-speed transmission.[0002]Electrical connectors used to plug a communication cable into an electrical system may include a housing that contains several conductors that form differential pairs. The differential pairs are configured to connect with corresponding differential pairs in a mating connector of the electrical system (e.g. a port) when the pluggable and mating connectors are engaged. However, pluggable connectors that are currently used may have certain limitations due to unwanted electromagnetic coupling between the differential pairs. For example, the operating speeds of M-series pluggable connectors are limited to transmission rates of less than one gigabit per second. If current M-series pluggable connectors were to operate at speeds above one gigabit / s, the unwanted electromagnetic coupling between the differential pairs would harm signa...

[0007]Optionally, the grounding member has a cross-section taken perpendicular to the central axis. The cross-section of the grounding member may have a thickness that decreases as the grounding member extends toward the central axis. ...

Problems solved by technology

However, pluggable connectors that are currently used may have certain limitations due to unwanted electromagnetic coupling between the differential pairs.

For example, the operating speeds of M-series pluggable connectors are limited to transmission rates of less than one gigabit per second.

If current M-series pluggable connectors were to operate at speeds above one gigabit / s, the unwanted electromagnetic coupling between the differential pairs would harm signal integrity and the performance of the connector.

For example, the increase in near-end crosstalk (NEXT), far-end crosstalk, and / or return loss may render the connector unable to meet industry requirements.
